MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 448,265, dated March 17', 1891. Application filed February 28, 1890. Renewed February 4, 1891. Serial No. 380,128. (No model.)

To aZZ whom it may concern:

Be it known that I, BRUNO Sonwnronu, a subject of the King of Saxony, residing at l-luchholz, Kingdom of Saxony, German Empire, have invented an Improved Music-Leaf Turner, of which the following is a specification.

This invention relates to an improved musieleaf turner which is operated by a pressure of the hand, knee, or footupon a key or treadle.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view of my improved music-leaf turner. Fig. 2 is a front view of the lifting mechanism. Fig. 8 is a side view of the same, and Fig. l a perspective view of the upper part of a traveling rod with running sheave.

The letter (t represents a desk, musical instrument, or support of a music-book. To the upper corners of this desk a rail 0 is secured or removably fitted. This rail extends in a downwardinclined plane from the right to the left and has a slight forwardly-extemling curve at its center. The rail 0 may be composed of two sections joined to each other, as at o, for the purpose of more conveniently storing the. rail when out of use.

d is a lifting-rod, preferably bent at its lower end and provided with a key 6, that may be reached by the hand, or the lifter may be provided with a treadle or be operated by the knee. On forcing the key e down the rod d will be lifted against the action of a spring f. The rod (Z may also be formed in two sections secured to each other, as at s. The rod (Z is guided through a lug g, as at a secured to the rear of the desk (1..

72. is a guide-rod supported by a socket of the lug g, and thus firmly held in place. The upper end of rod 7b is bent to form an arm i, projecting first forward and then upward. It terminates in a pin 7b, which engages the rail 0 to steady the rail in its position. The bent part i of rod 71. further carries a pivoted crossbar 25, having near each end an upwardly-pro jecting pin 79 and Z. The upper part of the liftin -rod (Z extends parallel to the bent arm '2', as sdlown. The free end of rod (Z is pivotally connected to one end of the cross-bar Z, adjacent to the pin Z.

on m are metal rods bent at the upper ends to receive the trnnnions of running sheaves n, which slide on rail 0. A bent arm 0, projecting from rod on and passing across the front of sheave '22, keeps the several rods m properly distanced from each other. From the rear of each rod in there projects also a pin 1), that engages the pin 7c of cross-bar t. Said pin 7; stops the first traveling rod m of the series by extending into the path of pin 1). 3y pressing down keye the rod (Z will be lifted, as described, the pin Z will be forced up, while pin 7.; will be forced down to clear the pin p of the traveling rod on. The rurr ning sheave n of said rod is now free to roll down the inclined rail 0. The second rod m, instead of rolling down together with the first one, is stopped by the raised pin Z. As soon as the key (2 is released the lifting-rod (Z is returned to its normal position by the springf, the pin Z is lowered, and the pin Zr is raised. The rod nz consequently is set free from pin Z, but is stopped by pin 70, that engages pin p, as before described, until the key is again depressed.

The sheets of music are held in position by a wire q, the upper hooked end '2' of which embraces the upper edges of the leaves.

To prevent the traveling rods in from striking against the frame at the end of their motion, a movable arm a: is provided at the lower left-hand corner of the desk, the upper end of which is connected to the frame by a slack cord, as at u. This cord will receive the impact from the rods m. The loose disk or ring .2, slipped over the arm .90, prevents said arm from striking the desk when the traveling rod on falls against the cord. In setting the apparatus all the rods m are carried up the rail 0, where they are held in position by the pin 7.; of cross-bar Z, that engages the pin 11 of the foremost rod 111. The lower ends of rods mare slipped between the music-sheets, so that one rod between every two pages of music. Every descent of the key 6 or lift of the rod (Z sets the foremost traveling rod 171. free to roll down the rail 0, as described, and the rod being preferably weighted turns the sheet over from the right to the left while Ioo passing down. To prevent the traveling rods from being stopped by the fold of the book, a series ofrods m, having pulleys n and pins the rail 0 has a curve over said fold. In this p, and with lifter (Z, and pivoted cross-arm 15, way the rods pass clear of the fold of the having pins 70 Z, substantially as specified. book while running down the rail. In testimony whereof I sign my name, in What I claim is the presence of two subscribing witnesses,

2. The combination of an inclined rail with 1. The combination of an inclined rail with this 18th day of September, 1889. a series of rods m, having pulleys n that engage said rail, and with a lifter d, and a stop operated by said lifter and engaging the rods m, substantially as specified.
